There were some coins in Packet Y and Packet Z. After Warren transferred
35 of the coins from Packet Y to Packet Z, the ratio of the number of coins in Packet Y to that in Packet Z changed to 1 : 8. Find the ratio of the numbers of coins in Packet Y to the number of coins in Packet Z at first.
|
Packet Y |
Packet Z |
Before |
5x1 = 5 u |
13 u |
Change |
- 3x1 = - 3 u |
+ 3 u |
After |
2x1 = 2 u |
|
Comparing Packet Y and Packet Z in the end |
1x2 = 2 u |
8x2 = 16 u |
The number of coins in Packet Y in the end is repeated. Make the number of coins in Packet Y in the end the same. LCM of 2 and 1 is 2.
At first
Packet Y : Packet Z
5 : 13
Answer(s): 5 : 13
